Impact:
1:convert all remain take_over_console to do_take_over_console
2:update take_over_console to do_take_over_console in comment
Commit dc9641895abb ("vt: delete unneeded functions
register_con_driver|take_over_console") delete take_over_console,
but forget to convert remain take_over_console's users to new API
do_take_over_console, this patch fix it.

Sorry for my mistake, I believe I do the full
kernel source find|grep, but the reality is I
forget take_over_console.
I will send the patch to update DOC tonight.
